How can i create a variable integer named X, range between ( - 100 to 1000)

Answer 1

No, you can't because range of variable is decided by type of compiler used (16 bit,32bit ,or 64bit).

Answer 2

Do you mean create an int named x set to a random value between 100 - 1000?

import java.util.Random;

public class Program
{
public static void main(String[] args) {
int max = 1000;
int min = 100;
int n = new Random().nextInt(max - min) + min + 1;

System.out.println(n);
}
}

This should result in what you're looking for if that is the case.

Or better yet:

import java.util.concurrent.ThreadLocalRandom;

public class Program
{
public static void main(String[] args) {
int max = 1000;
int min = 100;
int n = ThreadLocalRandom.current().nextInt(min, max + 1);

System.out.println(n);
}
}

Answer 3

No, you cannot define a new range for a variable.

However, you can use setters to simulate this manually.

Example/

class Program{

int x;
// my var

public void setX(int newX){
if (newX <= - 100)
x = - 100;
else if (newX >= 1000)
x = 1000;
else
x = newX;
}
}

Now if I changed the variables value:

setX(x - 10000);
// x = -100
